Answer:
Try sketching an image of the rectangle. Area = length x width. To find the perimeter you would add up the length of all four sides.
Step-by-step explanation:
Answer:
9 : 3
Step-by-step explanation:
To get from 21 to 3 we divided 21 by 7, therefore we have to do the same to the other side and so we get...
63 / 7 = 9
Therefore 63 : 21 = 9 : 3
Answer: The perimeter of the yellow rectangular tile is 240 centimeters.
Explanation: To find the answer, write this information as a proportion since we know that the rectangles are similar.
(Assume that in both ratios, the numerator is the length of the rectangle, and the denomiator is the perimeter. Also, the left side is for the green rectangle and the right side is for the yellow rectangle.)
Since we don’t know the perimeter of the yellow rectangle, let’s express it as x.
24/80 = 72/x
A good shortcut is to cross multiply. To do this, multiply the left numerator by the right denominator, and the left denominator by the right numerator, and set both products equal to each other.
24 • x = 80 • 72
Simplify the equation.
24x = 5760
Divide both sides by 24.
x = 240
Since x = 240, we know that the perimeter of the yellow rectangular tile is 240 centimeters.

Answer:
25
Step-by-step explanation:
total books = (books per box) × (number of boxes)
number of boxes = (total books)/(books per box) = 625 /25 = 25
She needs 25 boxes to move all the books.
X=initial deposit amount.
we have to add to the initial deposit amount the incomes and subtract the withdrawal
x+($75.5+$55.25)-($25.15+$18.65)=$210.85
Now we solve this equation.
x+$130.75-$43.8=$210.85
x+$86.95=$210.85
x=$210.85-$86.95
x=$123.9
Answer: his initial deposit amount is $123.9
